贱人不贱渐渐贱
[jiàn rén bù jiàn jiàn jiàn jiàn]
Though literally meaning 'a low-life person doesn’t devalue and slowly becomes less valued,' it is quite complex. In a modern context, it humorously reflects that even though people call someone low-life ('cheap' in another sense), such a one would still maintain their self-esteem while gradually growing more self-confident.
